If you can dominate the line of scrimmage, it's like your side of the ball is playing downhill against your opponent. It's a legit game-changer.

It's much, much tougher to do that on the defensive side of the ball, where you're starting out outnumbered, outsized and with more elaborate schemes being run at you every year.

If you're a clogger, all you have to do is to be incredibly hard to move. That's very important but it doesn't require a tremendous amount of skill or technique.

But if you're expected to play as a penetrating three-tech or as a five-tech in general, you're not only responsible for more space, you're going up against tackles more often and you're expected to do far more things, such as disrupting the pocket while still anchoring in the run game. It requires tremendous strength, athleticism, and technique.

In short, it's a game-changer in your favor and it's very, very hard to do.

That doesn't make them more important than the other 18 or 19 positions on the field.

Teams that spend high choices on DTs tend to do worse than teams that spend their high choices elsewhere.
